Abstract

Strange and multistrange baryon and antibaryon production is a useful probe into the dynamics of the hot hadronic matter created in central heavy ion interactions. Relative production yields and transverse mass spectra are presented for Λ, Λ , Ξ − and Ξ + hyperons produced in central sulphur-tungsten interactions at 200 GeV/ c per nucleon.
